The foundries still have the process in place for making DDR4, so since there’s demand they will keep making the product. It costs money to replace the machines in the facility to switch it to ddr5 or hbm, so the math only makes sense for a little while longer.
Because the factories are already set up to make DDR4. Retooling to make DDR5 will cost a lot of money and take a lot of downtime for which the factory isn’t making anything. So the companies are extending the life cycle of the DDR4 production lines, without needing to upgrade things or retrain workers. As long as people are buying it, then there’s money to be made by staying open.
It’s like being the burger restaurant next to the steak restaurant when the line for the steak restaurant is 3 hours long. You’ll get a lot of spillover from people who don’t want to wait, and you can benefit from that without necessarily turning into a steak restaurant yourself.
Wrong, memory companies have moved on to DDR5, they need to retool back yo to reproduce DDR4. The only problem is the semi fabs sold out of the ddr5 chips to AI companies for their builds.
Do you mean the actual packaging of silicon dies and putting them into DIMMs? Yeah, they had to revert back, but that’s because a lot of the memory silicon that’s only good for DDR4 never shut down, and any silicon memory that is good for DDR5 is also getting claimed up for non-DIMM memory (e.g., memory packaged with logic chips rather than sitting on its own package in a DIMM or even soldered to the board).
Basically, previous generations’ silicon fabrication tech is still going, and there are still buyers of that last generation product.
Can someone that explain this to me? Why are companies choosing to make older parts available again instead of just making the new shit?
DDR4 slower therefore less demand from AI
